Product Options


MASS 6000 mass flow transmitter is based on the latest developments within digital signal processing technology engineered for high performance, fast flow step response, fast batching applications, high immunity against process noise, easy to install, commission and maintain. The MASS 6000 transmitter delivers true multiparameter measurements i.e.: Mass flow, volume flow, density, temperature and fraction flow.

The MASS 6000 Ex d transmitter is manufactured in stainless steel (AISI 316L) and able to withstand harsh installation conditions in hazardous applications within the process and chemical industry. The conservative choice of material guarantees the user a low cost of ownership and a long trouble-free life-time. The Ex d can be compact mounted on all sensors of type MASS 2100 DI 3 to DI 40, and can be used in remote version for all types of MASS 2100.


The mass flow transmitter is designed in an Ex d compact stainless steel enclosure which can be compact mounted on the MASS 2100 sensor range DI 3 to DI 40, and remote mounted for the entire sensor series. The MASS 6000 Ex d is available as standard with 1 current, 1 frequency/pulse and 1 relay output and can be fitted with addon modules for bus communication.

  • Flameproof "d" enclosure
  • Enclosure stainless steel, IP67/NEMA 4X as compact and IP66/NEMA 4 as remote
  • Supply voltage 24 V AC/DC
  • MASS 6000 Ex d is ATEX approved together with all MASS 2100 sensors

Heating Jacket

All the sensors MASS 2100, DI 3 to DI 40, can optionally be equipped with a heating coil in order to prevent solidification of sensitive fluids during down-time or periods between discontinuing processes. This provides an alternative to the costly electrical heating normally used, as it gives the freedom to choose either hot water, superheated steam or hot oil, to maintain a constant temperature inside the sensor.


  • High accuracy better than 0.1% of mass flow rate
  • Large dynamic turn-down range better than 500:1
  • Single continuous tube design, with no internal welds, reductions or flow splitters offers optimal hygiene, safety and CIP cleanability for food & beverage and pharmaceutical applications
  • Markets biggest wall thickness, ensuring optimal life-time and corrosion resistance and high-pressure durability
  • Densitometer performance available through a density accuracy better than 0.0005 g/cm3 with a repeatability better than 0.0001 g/cm3
  • Full bore design provides lower pressure loss due to same internal
    diameter throughout the entire sensor.
  • Balanced pipe design with little mechanical energy loss, ensures optimal performance and stability under non-ideal and unstable process conditions (pressure, temperature, density changes etc.)
  • 4-wire Pt1000 temperature measurement ensures optimum accuracy on mass flow, density and fraction flow
  • Multi-plug electrical connector & SENSORPROM enables true "plug & play". Installation and commissioning in less than 10 min.
  • Intrinsically safe Ex-design ia IIC as standard, making service in hazardous area possible without having to demount the sensor if a compact Ex d transmitter needs service
  • Sensor pipe available in high-quality AISI 316L stainless steel W 1.4435 or Hastelloy C22 W 2.4602 offering optimum corrosion resistance
  • Centre-block design decouples process noise from the environment such as vibrations, pulsations, pressure shocks etc. making installation flexible and versatile
  • Rugged and space-saving sensor design in stainless steel matching all environments
  • Uniform sensor interface matching all transmitter versions at the same time whether it is compact IP67/NEMA 4X, compact Ex d or remote installation, one sensor fits all
  • High-pressure program as standard
  • Sensor calibration factor is also valid for gas measurement

No, all of our flowmeters are competitively priced and rental is an ideal option for cutting costs to a fraction of a full priced new flowmeter.
No problem. The quick start guide is designed to make installing the flow meters a simple task. Everything you require for set up will be found in the peli-box supplied with the flowmeter.
Every flow meter is tested upon shipping and return as part of our ISO9001 procedure. Also, as part of this procedure, the flow meter is calibrated once a year. If a copy of the calibration certificate is needed let us know.
The flow meters typically provide an accuracy of ±1 to 2% of rate, so if you are measuring 100l/sec then the accuracy is between 98-102l/sec.
We are here to help. If the self-help and quick start guides do not help, then call one of our technical support engineers on +44 (0) 1527 882060. We have supplied and supported many clamp on rental installations throughout Europe.
First, contact us for a quote. If you are happy with the quote then send us a purchase order. Or alternatively call us with credit card details and fill out and send us a rental agreement form.
If the stock is permitting, and all paperwork is received by 12pm then flow meters can usually be available the next day.
The minimum hire period for flow meters is one week.
Once you have the meter you can rent it for as long as you need it. However, it would help if you can let us know that you wish to extend the rental period. Upon return the meter is off-hired and once checked and tested, an invoice will be issued to you. Also, if you extend your rental past a 4, 8 or 12 week rental threshold, then you are entitled to a discount.
You are only charged for the period of time for which you have the flowmeter. So, if a flowmeter is returned 3 days late you are only charged for 3 extra days, and each of these days is charged at one fifth of the weeks hire cost.
Normally, you will use your own courier but if you have any problems let us know and we can arrange a pick up the day after you notify us, but you will be charged for the carriage and this cost will be added to the invoice.
Without exception, all our flow meters are tested. If you need a 110v plug instead of the standard 230v plug let us know.
All of our standard transducers will do -40degC to +150degC, but this will depend on your application.
  • Liquid: below 50mm CFLP transducers are required, 50-1000mm CRS-402 transducers and 150-8000mm CRS-401 transducers. All the bits you need can be supplied, and delivered with the meter.
  • Gas: below 80mm CRS-402 is required, for 80-300mm the CRS-401/CRV-310 and for above 300mm the CRW-312 transducers are required.
  • High temperatures: For liquid we can measure +450degC for liquid and for gas/steam +250degC. But please consult RS Hydro.
Of course, we make a small surcharge for each set of transducers. Most applications only require one set, but on occasion some people may require two, for more diverse pipe sizes and applications.
An ultrasonic wall thickness gauge, that measures to within 0.05mm, is provided as standard with all flow meter rental packages.
The screendump facility on the integrated dataloggers on all our flow meters, allows you to photograph any screen and download it to your pc.
After the equipment has been shipped, it is the responsibility of the hirer. However, in our experience it is rare that any of our flow meters are damaged. Our flow meters are tough, as well as accurate, and reliable.
We have hired more ultrasonic clamp on flow meters than any other company in Europe. We are now one of the world's largest distributors of GE Panametrics flow meters. We always review your application before hire so no unwanted surprises are encountered. Every effort has been made to make your flow meter hire and enjoyable experience: quick start guides to help you set up with ease, online videos for further help, rugged packaging for extra durability anywhere, and real flow engineers available for online/telephone support.
